High quality: Our trumpet mouthpieces are made of brass, offering a comfortable touch and excellent sound. The silver plating makes them easy to clean and maintain. Value Pack: The package includes 3 trumpet mouthpieces (1x 7C, 1x 5C, 1x 3C). This set is suitable for various playing situations and skill levels. Precise Size: These mouthpieces come in three sizes ranging from small to large. Features such as the outer rim, inner cup, inner diameter, and backbore are precisely crafted. The engraved markings allow quick identification of each type. Beginners are recommended to start with the 7C, which produces sound more easily. As lip strength improves with practice, players can progress to the 5C and then the 3C, which is commonly used by professional trumpet players. Application: These mouthpieces are compatible with most standard trumpets and are ideal for use in schools, concert halls, bars, homes, band practice areas, and learning environments.
